Overview of this book

PostgreSQL is a powerful, open source database management system with an enviable reputation for high performance and stability. With many new features in its arsenal, PostgreSQL 10 allows users to scale up their PostgreSQL infrastructure. This book takes a step-by-step, recipe-based approach to effective PostgreSQL administration. Throughout this book, you will be introduced to these new features such as logical replication, native table partitioning, additional query parallelism, and much more. You will learn how to tackle a variety of problems that are basically the pain points for any database administrator - from creating tables to managing views, from improving performance to securing your database. More importantly, the book pays special attention to topics such as monitoring roles, backup, and recovery of your PostgreSQL 10 database, ensuring high availability, concurrency, and replication. By the end of this book, you will know everything you need to know to be the go-to PostgreSQL expert in your organization.

Hot logical backups of one database

Logical backup makes a copy of the data in the database by dumping the content of each table as well as object definitions for that same database (such as schemas, tables, indexes, views, privileges, triggers, constraints, and so on).

How to do it...

The command to do this is simple. The following is an example using a database called pgbench:

pg_dump -F c pgbench > dumpfile

Or, you can use the following command:

pg_dump -F c -f dumpfile pgbench

You can also do this through pgAdmin 4, as shown in the following screenshot:
